Winter has arrived, and in the blogosphere that can only mean one thing- it's time once again for the latest epic quiz from Dennis Cozzalio's must-read blog, Sergio Leone and the Infield Fly Rule. Dennis has a tradition of attributing his quizzes to famed educators of filmdom, and this one's got a doozy- Ball of Fire Bertram Potts, who's always dressed up like a million-dollar trooper. So whether you're blogging from work on a slow afternoon or looking to fill some of that end-of-year vacation time, take a trip to the hallowed halls of SLIFR University, sharpen those No. 2 pencils, and take Professor Bertram Potts' Hella Homework For the Holidays Christmas Break Quiz. Check it out- it's super duper!
